suppose a block is broadcasted that would fork off a previous block. it seems nodes can't immediately reject this because it might actually be that the fork is longer or becomes longer than what they currently think is longest chain, right?

and i would think they dont maintain state snapshots of the entire system account balances at every node. so...does this mean that to validate it, they essentially have to apply every single transaction replayed from the start?
